A fire engulfed a tent being used as a dormitory for workers at a construction site in Istanbul on Sunday , killing 14 people. The workers were housed in a large tent at the construction site of a supermarket, said Necmi Kadioglu, the mayor of Esenyurt district. "We suspect that the fire might have originated from an electrical heater," he said. Turkey's state-run television reported the fire may have been sparked by a short circuit. Firefighters recovered the bodies working under floodlights. An adjacent tent was also burned, but it was not clear if any of the workers had been staying there.
